You are being watched..T-Ray Vision...

New technology that can "see" through clothing and detect what's underneath can now be used to scan crowds, making it a potentially effective tool to prevent terrorist attacks in public places.

The camera can see through people's clothes from up to 25 meters away, detecting objects.

The ThruVision T5000 camera picks up Terahertz rays, or T-rays, which are naturally emitted by all objects and can pass through fabric or even walls.

The camera can then image metallic and non-metallic objects hidden under clothing on still or moving subjects without revealing any body detail, according to its British manufacturer, ThruVision Limited.

While similar technology is being unveiled at airports around the world, the T5000 is designed to be used in large, open areas. With a range of 25 meters, the T5000 can screen people in public places, thus avoiding bottlenecks at border crossings or security checkpoints.

It also means people can be screened without knowing it.

Amid privacy concerns, ThruVision Chief Executive Clive Beattie said the image produced by the camera did not reveal detailed anatomy.

"It's almost a glowing light bulb," Beattie told CNN. "You don't see the detail that people might be concerned about."

Explosives, liquids, narcotics, weapons, plastics, and ceramics can all be detected by the camera's imaging technology, which the company says is completely safe. Unlike X-rays, the T5000 does not emit radiation -- it only picks up on it.
